My friend is having some trouble with his twitch stream. Every time he streams, he runs into some blurring and pixelation even though he's using a normal bitrate and has decent enough internet to run a smooth 720p 60fps stream.

clip from his stream for example: twitch.tv/ayjstn/clip/AuspiciousP...;sort=time


His PC Specs:

- MSI X470GPLUS
- AMD RYZEN 2600X Processor
- TEAM 8GB T-FORCE VULCAN DDR4 RAM (1 Stick)
- ZOTAC GEFORCE GTX 1060 MINI
- CRUCIAL BX300 120GB SSD + 2 TB EXTERNAL HD
- EVGA 500W Power Supply

Stream Settings:

- NVENC
- CBR
- Bitrate 3500
- Keyframe Interval 2
- Preset :Quality
- Profile: Main
- Level: Auto
- Two Pass Encoding is Checked
- GPU: 0
- B FRAMES: 2

I mean in all honesty pc specs aren't what is keeping him back, IMO it doesn't seem like it's a hardware issue

I'd say his internet isn't good enough to run 720p 60fps at all times, maybe is parents use the internet and take some bandwidth..

I'd say he'd either have to keep them off the internet while he streams or just upgrade internet and fork some cash over to help.

He could try using Streamlabs OBS which does have an improved Encoder (Not by much), Also he could try going into video settings and setting his Downscale filter to Lanczos. Thats what i use and it runs fine, I also run at 5k Bitrate though which does help when using the NVENC encoder.

Several variables when it comes to streaming. Twitch is rather bad for streaming too, they force non partnered or affiliated streamers down to a max of 720@60. Sure you can force your way past it if your internet and hardware are all amazing, otherwise not so much.

Streaming Factors:
Internet connection speed (it's not download... it's upload.)
Software being used
Background processes currently running
Hardware - overheating = throttling = drops in performance
Wifi or wired?

Stream Settings to try:
Bitrate: 6000 (max Twitch allows)
Change in game settings (major thing that can kill any game's fps is AA of any kind.)
Change downscale filter to Lanczos
Try x264 instead of Nvenc
Turn on look-ahead set GPU to 8 and work down. Max b-frames to 4, every 2 down on GPU reduce b-frames by 1.
Change stream quality, and scaling.


With his PC there is some hardware limitation. With 8GB of RAM and a lot of games chewing that up, 16GB has for a lot of games become the new standard. Especially if you want to be able to run discord, teamspeak, chrome, any monitoring software, OBS, streamlabs, muxy, etc all at the same time. RAM does play a factor. Otherwise, decent PC, and good luck.
